WIRE-GRIP.

SPECIFICATION forming part of Letters Patent No. 708,314, dated September 2, 1902.

Application filed January 27, 1902. Serial No. 91,330. N modem T0 at whom it may concern:

Be it known that we, JOSEPH D. CAMPBELL, residing in Delaware, in the county of Delaware, and ROBERT C. KYLE, residing at Go lumbus, Franklin county, State of Ohio, citizens of the United States, have invented a certain new and useful Improvement in WVire- Grips, of which the following is a specification.

Our invention relates to the improvement of wire gripping or clamping devices; and the objects of our invention are to provide an improved grip or clamp of this class of superior construction and arrangement of parts which will facilitate the stretching of a wire, to construct said improved wire-grip in a simple and inexpensive form and to embody therein means for insuring a firm hold on a wire to be stretched, and to produce other improvements, the details of which will be more fully pointed out hereinafter. These objects we accomplish in the lnannerillustrated in the accompanying drawings, in which Figure 1 is a side elevation'of ourimproved wire-grip. Fig. 2 is a face view of the same, and Fig. 3 is a detail view of one of the gripsections.

Similar numerals refer to similar parts throughout the several views.

In carrying out our invention we employ two grip or clamp sections or members, which are indicated, respectively, at 1 and 2. The outer grip member 1 is in the nature of a bar, the inner end portion 1 of which is inclined outward from the body of the bar at an obtuse angle with the latter. In the outer end portion of the upper side of the bar 1 is formed a vertical recess 3, which is flaring toward its inner end and which results in the formation of a substantially hook-shaped outer end 1 of the body 1. One face of the body 1 is, as indicated at 4, formed with a rounded de pression or recess which leads from the notch or recess 3 inward, while a similar recess is formed on the opposite side of the hook portion 1 of the body leading from said recess 3 outward, this recess being indicated by the dotted line in Fig. 1. The outturned wing or end portion 1 of the section 1 is formed with a vertical mortise or slotted opening 6. The inner grip section or member 2 is in the nature of a slightly-curved bar, the forward end of which is enlarged vertically to form a head 7, which when the body of the bar is inserted in the opening 6 in the manner shown prevents a complete passage of the bar therethrough. The section or member 2 is provided at a point adjacent to its head 7 with an upper side notch or recess 8, and the opposite extremity or inner end of the section 2 is adapted to have engaged therewith the end link of a pulling-chain 9.

In utilizing the above-described invention for the purpose of stretching or pulling taut a wire, such as is indicated at 10, the wire is, as shown in Figs. 1 and 2, threaded or caused to pass through the notch or recess 3 of the outer section, from which recess said wire is carried inward or rearward along the inner face of the section 1 and passes through the notch or recess 8 of the section 2. This being accomplished, it will be seen that a pull on the chain 9, and a consequent pull on the section 2, will serve to bendthe wire between the notched portion of said section 2 and the projecting portion 1 of the section 1. The pull being approximately in the direction of the length of the wire, it is obvious that a slight double or compound bend will be imparted to the wire where it engages opposite sides of the recess 3, this bend, in conjunction with the slight bend imparted by the clamping of the sections 1 and 2, being such as to insure a firm grip upon the wire and permit of the latter being drawn taut or stretched and in this operation withstanding great strain. The formation of the face recess 41 and the corresponding recess on the opposite side of the section 1 and on the opposite side of the notch or recess 3 permits of the wire being passed through said recess without imparting a bend thereto of undesirable degree.

It will be observed that our improved wiregripping device is simplein construction and that the same may be easily and readily employed for the purpose of stretching or drawing wires taut.

Having now fully described our invention, what we claim, and desire to secure by Letters Patent, is-

1. In a wire-grip, the combination with the section 1 having its inner end portion bent outward at an angle therewith and having its its outer end portion and an opening in its forward end portion formed with an upper outwardly-bent end portion, of a section 2 15 side notch or recess, of a separately-formed comprising a curved bar adapted to pass section 2 the body of which is adapted to pass loosely through the opening at the inner end 5 loosely through an openingin said outwardlyof the bar 1, said section 2 having an enlarged bent portion of the section 1, said section 2 head portion 7 and upper side notch or recess having an enlarged head portion 7 and an up- 8, substantially as specified.
